# RouteInfo

`public final class RouteInfo`
`extends Object` `implements Parcelable`

java.lang.Object
↳ | android.net.RouteInfo

Represents a network route.

This is used both to describe static network configuration and live network configuration information. A route contains three pieces of information:

- a destination `IpPrefix` specifying the network destinations covered by this route. If this is `null` it indicates a default route of the address family (IPv4 or IPv6) implied by the gateway IP address.
- a gateway `InetAddress` indicating the next hop to use. If this is `null` it indicates a directly-connected route.
- an interface (which may be unspecified).

Either the destination or the gateway may be `null`, but not both. If the destination and gateway are both specified, they must be of the same address family (IPv4 or IPv6).

## Summary

### Inherited constants
From interface `android.os.Parcelable`
`int` | `CONTENTS_FILE_DESCRIPTOR` Descriptor bit used with `describeContents()`: indicates that the Parcelable object's flattened representation includes a file descriptor.
`int` | `PARCELABLE_WRITE_RETURN_VALUE` Flag for use with `writeToParcel(Parcel, int)`: the object being written is a return value, that is the result of a function such as "`Parcelable someFunction()`", "`void someFunction(out Parcelable)`", or "`void someFunction(inout Parcelable)`".

### Fields
`public static final Creator<RouteInfo>` | `CREATOR` Implement the Parcelable interface.

### Public methods
`int` | `describeContents()` Implement the Parcelable interface
`boolean` | `equals(Object obj)` Compares this RouteInfo object against the specified object and indicates if they are equal.
`IpPrefix` | `getDestination()` Retrieves the destination address and prefix length in the form of an `IpPrefix`.
`InetAddress` | `getGateway()` Retrieves the gateway or next hop `InetAddress` for this route.
`String` | `getInterface()` Retrieves the interface used for this route if specified, else `null`.
`boolean` | `hasGateway()` Indicates if this route has a next hop (`true`) or is directly-connected (`false`).
`int` | `hashCode()` Returns a hashcode for this `RouteInfo` object.
`boolean` | `isDefaultRoute()` Indicates if this route is a default route (ie, has no destination specified).
`boolean` | `matches(InetAddress destination)` Determines whether the destination and prefix of this route includes the specified address.
`String` | `toString()` Returns a human-readable description of this object.
`void` | `writeToParcel(Parcel dest, int flags)` Implement the Parcelable interface

### Inherited methods
From class `java.lang.Object`
`Object` | `clone()` Creates and returns a copy of this object.
`boolean` | `equals(Object obj)` Indicates whether some other object is "equal to" this one.
`void` | `finalize()` Called by the garbage collector on an object when garbage collection determines that there are no more references to the object.
`final Class<?>` | `getClass()` Returns the runtime class of this `Object`.
`int` | `hashCode()` Returns a hash code value for the object.
`final void` | `notify()` Wakes up a single thread that is waiting on this object's monitor.
`final void` | `notifyAll()` Wakes up all threads that are waiting on this object's monitor.
`String` | `toString()` Returns a string representation of the object.
`final void` | `wait(long timeout, int nanos)` Causes the current thread to wait until another thread invokes the `notify()` method or the `notifyAll()` method for this object, or some other thread interrupts the current thread, or a certain amount of real time has elapsed.
`final void` | `wait(long timeout)` Causes the current thread to wait until either another thread invokes the `notify()` method or the `notifyAll()` method for this object, or a specified amount of time has elapsed.
`final void` | `wait()` Causes the current thread to wait until another thread invokes the `notify()` method or the `notifyAll()` method for this object.
From interface `android.os.Parcelable`
`abstract int` | `describeContents()` Describe the kinds of special objects contained in this Parcelable instance's marshaled representation.
`abstract void` | `writeToParcel(Parcel dest, int flags)` Flatten this object in to a Parcel.

## Fields

### CREATOR

    public static final Creator<RouteInfo> CREATOR

Implement the Parcelable interface.

## Public methods

### describeContents

    public int describeContents ()

Implement the Parcelable interface

Returns
`int` | a bitmask indicating the set of special object types marshaled by this Parcelable object instance. Value is either `0` or `CONTENTS_FILE_DESCRIPTOR`

### equals

    public boolean equals (Object obj)

Compares this RouteInfo object against the specified object and indicates if they are equal.

Parameters
`obj` | `Object`: the reference object with which to compare.

Returns
`boolean` | `true` if the objects are equal, `false` otherwise.

### getDestination

    public IpPrefix getDestination ()

Retrieves the destination address and prefix length in the form of an `IpPrefix`.

Returns
`IpPrefix` | `IpPrefix` specifying the destination. This is never `null`.

### getGateway

    public InetAddress getGateway ()

Retrieves the gateway or next hop `InetAddress` for this route.

Returns
`InetAddress` | `InetAddress` specifying the gateway or next hop. This may be `null` for a directly-connected route."

### getInterface

    public String getInterface ()

Retrieves the interface used for this route if specified, else `null`.

Returns
`String` | The name of the interface used for this route.

### hasGateway

    public boolean hasGateway ()

Indicates if this route has a next hop (`true`) or is directly-connected (`false`).

Returns
`boolean` | `true` if a gateway is specified

### hashCode

    public int hashCode ()

Returns a hashcode for this `RouteInfo` object.

Returns
`int` | a hash code value for this object.

### isDefaultRoute

    public boolean isDefaultRoute ()

Indicates if this route is a default route (ie, has no destination specified).

Returns
`boolean` | `true` if the destination has a prefix length of 0.

### matches

    public boolean matches (InetAddress destination)

Determines whether the destination and prefix of this route includes the specified address.

Parameters
`destination` | `InetAddress`: A `InetAddress` to test to see if it would match this route.

Returns
`boolean` | `true` if the destination and prefix length cover the given address.

### toString

    public String toString ()

Returns a human-readable description of this object.

Returns
`String` | a string representation of the object.

### writeToParcel

    public void writeToParcel (Parcel dest,
                    int flags)

Implement the Parcelable interface

Parameters
`dest` | `Parcel`: The Parcel in which the object should be written.
`flags` | `int`: Additional flags about how the object should be written. May be 0 or `Parcelable.PARCELABLE_WRITE_RETURN_VALUE`. Value is either `0` or a combination of `Parcelable.PARCELABLE_WRITE_RETURN_VALUE`, and android.os.Parcelable.PARCELABLE_ELIDE_DUPLICATES
